Shipping to Northern Ireland

TNT UK has made the following adjustments in accordance with the Windsor Framework. The Windsor Framework goes into effect 1 May 2025.

For shipments from Great Britain to Northern Ireland, TNT UK will require the usual customs declarations properties for all shipments. You must also print the commercial invoices for these shipments, just as you would for other cross-border shipments.

In the packages.products array:

description (must be detailed and describe the content accurately. Descriptions like "Gift" or "Merchandise" are not sufficient)
quantity
value (must include amount and currency)
harmonized_tariff_code
country_of_origin

For B2B shipments:

While not required to create a label successfully, you can declare the movement_indicator in the windsor_framework_details object. If you know the shipper and recipient UKIMS numbers, you should declare them in the tax_identifiers object in both the ship_to and ship_from objects.
If these values are not provided starting 1 May 2025, TNT UK's customs experts will identify whether the consignment is B2C or B2B and will contact you to obtain information regarding the shipment's risk indicator. UKIMS numbers will also be collected by TNT, if not provided when you create the label.
